NPS — Net Promoter Score
A metric that measures customer loyalty by asking one question: "How likely are you to recommend us?"
NPS (Net Promoter Score) is measured on a 0-10 scale. Customers giving 9-10 are "promoters," 7-8 are "passives," and 0-6 are "detractors." NPS = % promoters - % detractors. AI voice agents improve NPS through instant response, consistency, and 24/7 availability. According to Deloitte, businesses integrating AI in service see a 3.5x increase in NPS within one year (Source: Deloitte AI Institute, 2024).
